Title: Evaluation of detrusor function and predicting the surgical outcome for cases of benign prostatic hyperplasia associated with acute urinary retention
Abstract: Objective To evaluate the detrusor function for cases of benign prostatic hyperplasia(BPH) associated with acute urinary retention(AUR),and to predict the surgical outcome.Methods Urodynamic parameters were analyzed preoperatively and postoperatively in 23 cases of BPH associated with AUR,evaluation of detrusor function(include detrusor stability,compliance,contractile function).These parameters were compared between successful and failed treatment groups.Results Among the 23 cases of BPH associated with AUR,detrusor insuability(DI) was found in 16 cases(69.6%),the amplitude of DI was(98±33)(5~168)cm H2O.Voluntary detrusor contractions were seen in 20 cases(87%).Bladder outlet obstruction(BOO) was diagnosed definitely in all cases.Four cases(17%) failed to void after operation and required catheterization.There were significant differences(P0.05) between 2 groups regarding age,DI,detursor compliance,cystometric bladder capacity,and contractility of detrusor muscle.Conclusion For BPH patients with AUR,pressure-flow studies undertaken within 10 days after retention are useful in predicting the surgical outcome.The higher amplitude of DI,the stronger the contractility of the detrusor muscle and the better the postoperative results.The abnormal increase of detrusor compliance and cystometric bladder capacity and absence of DI are possibly associated with a poor outcome after operation.
